Abstract：
The possible microscopic mechanisms of some exotic properties of ^6—11Li nuclei,especially for dripline nucleus ¹¹Li are investigated in the framework of Shell Model. The quadrupole moment of the ground state of ⁶Li is primarily sensitive to the tensor components of interactions. The electromagnetic transition probabilities of the first excited states of ^6—8Li nuclei are extremely enhanced. The collectiveness possibly results from cluster structures. In the vicinity of 3≤Z ≤5 and N≈8,there may exist the phenomenon of crossed-shell excitation and/or N＝8 shell gap disappeariance.
